All of the fighters competing at the TUF 16 Finale show in Las Vegas were tested for performance enhancing drugs by the Nevada State Athletic Commission, and the results have returned.

According to a release from Nevada State Athletic Commission Executive Director Keith Kizer all fighters tested negative for the Dec 15 show.

The card was headlined by former TUF winner Roy Nelson, who has championed the drug testing cause for several fights now, also signing on to additional testing sponsored by VADA (Volunteer Anti-Doping Agency).

In total, 22 fighters were tested by the commission with all of them providing negative results for performance enhancing drugs.

The next major UFC card to take place in Las Vegas goes down this weekend for UFC 155 headlined by the heavyweight title fight between Junior Dos Santos and Cain Velasquez.
